A manual override device used to stroke a valve or limit its travel. The handwheel is sometimes referred to as a hand jack. It may be top mounted, side mounted, in-yoke mounted or shaft mounted and ...
angle valve
Industrial valves; Control valves
A valve for controlling the flow of a liquid or air; the fluid leaves at right angles to the direction in which it enters the valve.
critical flow
Industrial valves; Control valves
This condition exists when at a fixed upstream pressure the flow cannot be further increased by lowering the downstream pressure. This condition can occur in gas, steam, or liquid services. Fluids ...
inherent flow characteristic
Industrial valves; Control valves
It is the relationship between valve capacity and valve travel and is usually expressed graphically. It is derived from testing a valve with water as the fluid and with a constant pressure drop ...
reduced trim
Industrial valves; Control valves
Is an undersized orifice. Reduced or restricted capacity trim is used for several reasons. (1) It adapts a valve large enough to handle increased future flow requirement with trim capacity properly ...
cavitation
Industrial valves; Control valves
Occurs only in liquid service. In its simplest terms cavitation is the two-stage process of vaporization and condensation of a liquid. Vaporization is simply the boiling of a liquid, which is also ...
